Mechanical dilation botulinum toxin A injection and surgical myotomy with fundoplication for treatment of lower esophageal sphincter achalasia‐like syndrome in dogs

摘要

BackgroundMegaesophagus (ME) carries a poor long‐term prognosis in dogs. In people, lower esophageal sphincter (LES) achalasia is a rare cause of ME that may respond to targeted intervention. Dogs with lower esophageal sphincter achalasia‐like syndrome (LES‐AS) have been described recently, warranting investigation of analogous targeted treatment.
